METHOD OF ALLOCATING FREQUENCY BANDS TO DIFFERENT METHOD OF ALLOCATING FREQUENCY BANDS TO DIFFERENT CELLS, AND TDMA CELLULAR RADIO SYSTEM CELLS, AND TDMA CELLULAR RADIO SYSTEM

摘要

The invention relates to a TDMA cellular radio system, and a method of allocating available frequency bands to different cells in a TDMA cellular radio system wherein at least some of the receivers within the system employ interference cancellation methods for cancelling the effects of co-channel interference in a desired signal. To enable an efficient utilization of interference cancellation methods and the resulting capacity increase in the system, the frequency bands available for the cellular radio system are, according to the method of the invention, so allocated to different cells that groups (50-55) of adjacent service areas are formed in the system, each group employing the same frequency band within the service areas, whereby at least one co-channel signal interfering with the desired signal is significantly stronger than other co-channel interfering signals.
